SASI-I-FASTENER.

Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed May 19, 1914. Serial No. 839,490.

To all whom it may concern:

Be it known that 1, Feature "W. DAVID- soN, a citizen of the United States, residing at Abilene, in the county of Dickinson and State of Kansas, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification.

This invention relates to new and useful improvements in sash fasteners, and has for its principal object to provide adevice which will hold a window against movement in any desired position.

Another object of the invention is to provide a simple and effective sash fastener which may be easily and quickly put in place without materially changing the construction of the window.

A further object of the invention is to provide a device which will lock the upper and lower sashes in place in such a way as to prevent a person or persons from entering the house through the window and still permit the window to be adjusted for ventilation.

-With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which,

Figure 1 is a view of the interlor of a window showing the fastener in place, Fig. 2 is a vertical section taken on line 22 of Fig. 1. Fig. 3 is a view of the window casing showing the fasteners in place. Fig. i is an edge view of the sashes, Fig. 5 1s a horizontal sectional view of the fastener taken on line 55 of Fig. 3, and Fig. 6 is a vertical section taken on line 66 of Fig. 3.

Referring now to the drawings by characters of reference, the numeral 1 designates the wall of a building in which the window casing 2 is placed. This window casing 2 is provided with the usual slidable sashes 3 and 4: which are glazed in the usual way. The sashes 3 and 4 above mentioned include the usual frames 5 which are grooved as at 6, and secured to the groovededges are the cover plates 7 which are provided with a plurality of spaced transverse slots 8, which are designed to receive the locking plungers which will be more fully hereinafter described. A plurality of fasteners 9 which may be of any preferred type, are provided and are arranged to extend through the cover plates 7 to hold the same in place. The window frame 2 is pivoted with the recess 10 in the bottom wall of which is formed the transverse slots 11 which are arranged to receive the guides 12, in which the locking members, which will be more fully hereinafter described, are slidable. A pair of similar slots 13 are formed in the bottom wall of the recess and are arranged to form guides for the operating plungers as shown in Figs. 3 and 5. Secured to the bottom wall of the recess 10 is a suitable angle bracket lt which is preferably located centrally of one pair of slots 11 and 13 as shown in Fig. 3. Pivotally connected as at 15 to the upper terminal of the angle bracket 11 is the lever 16, one end of which is pivoted as at 17 to the locking plunger 18 which is slidable in the guide 12 hereinbefore described. A similar angle bracket 19 18 provided and carries at its free terminal the lever 20 having the plunger 21 pivotally mounted thereon. This lever is preferably slotted as at 22 to provide for longitudinal movement and easy operation of the device. The opposite end of the lever 20 is slotted as at 23 and is arranged to receive the pivot 24 by means of which the operating plunger 25 is pivotally connected to the lever. This operating plunger is provided with the reduced extension 26 which forms the lateral shoulder 27, the use of which will appear upon referring to Fig. 5. A suitable knob or gripping member 28 is carried by the free terminal of the reduced extension and is arranged to form a hand hold by means of which the operation of the device is controlled. A similar operating plunger 29 is pivotally connected to the free terminal of the lever 16 and said plunger carries at its reduced end the knob 80 to form a hand hold.

It will be evident from the foregoing that in use when it is desired to adjust the window, the knobs 28 and 30 are pulled outwardly, thus withdrawing the locking plungers 18 and 21 from their respective sashes and permitting the sash to be slid to the desired position. When the window has been properly adjusted the locking plungers are then forced into their respective slots thus holding the windows against movement.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as Will be Within the spirit and scope of the invention as defined in the appended claim.

Having thus described my invention, I claim:

A sash fastener including the combination with apertures near its opposite edges, a

support secured intermediate the ends of the plate, a lever pivoted to the support, said lever being slotted near each end, a tubular guide secured to the plate near one edge,

said guide registering with the aperture adjacent said edge, a locking pin slidable in Lthe guide, a pivot pin extending through the slot in the end of the lever and into the locking pin to pivotally and slidably hold the locking pin in operative position, a link connected to the oppositeend ofthe lever, said link being notched and arranged to engage one of the side Walls of the aperture adjacent the oposite edge, and a thumb piece carried by the link to enable the user to control the operation of the device' In te'stimonyvvhereofl aflix my signature inpresence of two Witnesses. g
